BORING-MACHINE.

Application filed May 10, 1905. Serial a. 259,779.

Specification of Letters Patent,

Patented March 19, 1907.

To all whom it may concern/.-

ranged downwardly upon an incline with re- Be it known that I, NATHANIELA. OoL- l spect to the portion 2 thereof, as shown.

LINs,a citizen of the United States, residing at Lela, in the county ofNoble, Territory of Oklahoma, have invented certain new and usefulImprovements in Boring-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to makeand. use the same.

This invention relates to a combined drilling or boring and bolt-holdermachine, and more particularly to that class of devices or machines fordrilling or boring holes in tires or for holding the bolts assed throughthe tires and fellies of a vehiclia or other wheel.

One object of the invention is to provide an exceedingly simple,comparatively inexpensive, durable, and eflicient device or machine forthe purpose named above.

Another object of the invention resides in the provision of a machine ordevice of the characterstated wherein an adjustment is arranged for theaccommodation of the device or machine for different size wheels.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed. out in the appended claim, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claim without departing from the spirit or sacrificing anyof the advantages of the present invention.

In the accompanying drawings, Figure 1 is aside elevation, partly insection, illustrating a machine or device applied to a wheel, the dottedlines indicating the position of the tension-lever 23 and the positionof the felly and its rim when the tension-lever is in the position shownin dotted lines. Fig. 2 is a view similar to Fig. 1, illustrating bydotted the beam lines the position of the beam in an adjusted latterhaving position. Fig. 3 is a perspective view of the device or machinedetached from a wheel.

Referring more particularly to the accompanying drawings, the referencecharacter 1 designates a portion of a vehicle or other upon wheel andthe reference character 2 a beam having a perforation 3 in one end andan up-' wardly-turned perforated arm 4 at its opposite end, the portion2 of the beam being ar- 2 the arm is bent outwardly, as at 6*, and

then perpendicularly, as at 6*, thence horizontal as at 6, and thenupwardly, as at 6 the latter portion being in direct alinement with theportion 6 and perforated, as at 6 for the reception of the thumb-screw8, having its inner end provided with a bearingplate or the like 9. Itwill be therefore understood that this peculiar formation or shape ofthe clamping-arm is for the purpose of permitting the portion 6* thereofto lie flush with one side of the felly, with the opposite side 6thereof flush with the opposite side of the felly, the said screw 8having its shank portion 8 screw-threaded for working fit with thescrew-threaded perforation 6 of the clamping-arm, with its inner endprovided with a plate 9, so that the clamping-arm may be tightly anddetachably engaged with one portion of the felly of the wheel.

Revolubly mounted in the opening 10 in the beam 2, in close proximity tothe clamping arm 6, is a drill shank 11, having a drill-point 12, fittedin its lower end with its upper end reduced, as at 13, to form theshoulder 14, upon which latter rests the perforated end 15 of the crankor operating element 16, the latter being provided with a handle 17. Inorder to firmly support the drill-shank in proper position with relationto 2, a stay-brace 18 is provided, the its upper portion 19 bentat anangle to its body portion and provided with a perforation or openingdesigned to embrace the upper end of the drill-shank 1 1, the lower end20 of the stay-brace being bent the opposite side of the body portion18, from which the portion 19 thereof is bent and arranged upon such anincline as to be fitted upon the upper face of the inclined portion 2 ofthe beam 2, the portion 20 being perforated for the reception of a bolt21, Which passes therethrough and through the beam 2, having a nut 22secured upon its lower end. It Will thus be seen that by reason of thestay-brace 18 the drill-shank is held rigidly in working position.

Pivotally disposed, by means of a pivot-pin a/at its angle in the upperperforated end of the arm 4, is an angular lever 23, whose shorterangular portion 24 is provided with a perforation 25 for the receptionof a pi vet-pin 26, which latter also pierces the hooked arm 27, Whosehooked portion 28 is designed to iit under the telly of the wheel whenthe device is in operation. It will now be understood that the lever 23is pivoted to the short arm 4 of the beam 2 and that the hooked arm 26is in turn p votally engaged in the free end of the short angularportion24 of the lever When it is desired to drill a hole in a metallic orother tire through the wheel, the clamping-arm 6 is, by means ol thesetscrew 8, clamped to the telly of the wheel, the clamping action ofthe arm taking place at such point along the telly as to have thedrill-point 12 disposed at the proper point for drilling. When theaforesaid elements have been disposed in the manner set forth, thehooked end 28 of the hook-arm 26 is disposed beneath the fell 7 of thewheel at a l l I I l l l l l distant point, as clearly shown in thedrawings, and the lever 23 is then turned toward the right, as shown indotted lines in Fig. 1, causing the telly and tire to be drawn to wardthe beam, as also shown in dotted lines. When these manipulations haveall been accomplished, the drill-shank is manipulated by means of itscrank or crank-handle for l l r l drilling purposes. If it be desired tohold a bolt instead of drilling a hole, the device is set up in themanner already set forth, the only di'll'erences residing in the(hanging of a bolt-holding tool in lieu of the drill-point 12.

There may be times when it is desired to adjust the beam 2 to dill'erentpositions, the inclined. portion 2 of the beam 2 aiding greatly in theadjustment of the beam toward the wheel, the prineipal adjustingteature, however, residing in the manipulatirm of the 'apnut 7 along thethreaded stem or shank portion 5 of the clamping-arm (i.

hat is elaimed is* A boring-111acl1ine comprising a beam having aperforation therein atone end and having an upwardly-turned arm at itsopposite end, an angle-lever pivoted at its angle to said arm, a hookedarm carried by the anglelever, a clamp-arm having a threaded stemengaged. in the opening ol the beam, a nut engaged with the stem abovethe harm, a drill-shank revolubly engaged in the beam between its ends,a drill earried by the lower end of the shank, and an operating-handlecarried by the upper end of the shank, said clamp and hooked armsextending below the beam, and being adapted for engagement with a bodyto be bored, said angle-lever and nut being operable to move the beamdownwardly.

In testimony whereof I allix my signature in presenee of two witnesses.
